Where to Get McDonald’s Secret Big Mac Sauce Free in Louisiana

McDonald’s is giving 10,000 bottles of their secret Big Mac sauce nationwide to introduce their new Mac Jr. and Grand Mac. But where can you get one in Louisiana?

The only McDonald’s location giving away the secret sauce in Lafayette is at 4555 Johnston St., but you can win a bottle today (January 26) by following and participating in McDonald’s live giveaway on Facebook, Instagram or Twitter.

If you’re near a participating McDonald’s you have to say the secret code “There’s a Big Mac for that” to a crew member or designated representative for a chance to get one of the exclusive bottles. They will be handed out on a first come, first serve basis.
